Use quotes around field names that start with an integer

[zeande]

In AL Code, it is required that any field name starting with an integer is wrapped in double quotes. If not, then the compiler throws a huge fit.

When saving a file, the CRS language extension currently removes quotes from these field names, resulting in uncompilable code. Even if using ">Save without formatting", the CRS extension still removes the quotes. This problem is described in #153

This fix changes the StringFunctions.encloseInQuotesIfNecessary method to also recognize such field names and enclose them in quotation marks.

would you see it possible to foresee a unit test?
